with appropriate personal protective equipment and following safe electrical
work practices.
Always wear eye protection, gloves, apron and mask when working with
batteries. Also remove any metal / conductive jewelry. Refer to the materials
safety data sheet (MSDS) for additional information including: hazards,

and use.
Precautions When Working With Batteries
• Consider your access to emergency medical attention, and work safely.
• Use caution to eliminate the risk of dropping a metal tool on the battery.
It could spark or short circuit the battery or other electrical parts and could cause
an explosion.
• Insulated tools are strongly recommended anytime you are working around
batteries.
• 1HYHUVPRNHRUDOORZDVSDUNRUࢊDPHQHDUWKHEDWWHULHV
• Remove all metal items, such as necklaces, rings, bracelets, and watches when
working with batteries. Batteries can produce a short circuit current high enough
to weld metal to skin, causing a severe burn.
• Ensure that someone is within range of your voice or close enough to come to
your aid when you are working near a battery.
• Wear complete eye / face protection and gloves. Avoid touching your eyes while
working near batteries.
• Never use or combine this battery with another dissimilar battery.
• Batteries are temperature sensitive. For optimum performance, they should be
installed in a stable temperature environment.
• Always recycle old batteries. Contact your local recycling center for proper
disposal information.
• Never wire the battery in series.

1.3 Battery Management System
Our lithium iron phosphate (LiFePO4) battery pack includes an onboard digital battery
management system (BMS). The BMS monitors voltage, current and temperature on
both an individual cell and battery pack level. If any of these measurements deviate
outside of their safe operating ranges, the BMS will actively work to correct the
deviation. If the deviation cannot be corrected automatically, the BMS will initiate a
self-protect shutdown by opening the internal contactor, disconnecting the battery
from the charger and loads.
2YHUFXUUHQWSURWHFWLRQȁ If the charge or discharge current of the battery exceeds
maximum permissible levels, the BMS will disconnect itself automatically. To recover
from a high current shutdown, remove the load from the battery, and then rest the
battery by turning the battery OFF and back ON.
2YHUFKDUJHSURWHFWLRQȁIf the battery`s voltage exceeds permissible levels the BMS
will disconnect itself automatically. To recover from a high voltage shutdown, remove
the charge source from the battery. The battery will automatically reconnect once the
charge source has been removed and the battery’s voltage drops down to permissible
levels.
2YHUGLVFKDUJHSURWHFWLRQȁIf the battery`s voltage drops below permissible levels
the BMS will disconnect itself automatically. To recover from a low voltage shutdown,
remove the load from the battery. At this point the battery should be charged
immediately. If the battery does not start on its’ own, you may need to put a charger
on the battery. If the battery is so discharged that the Low Voltage Shutdown cannot
be cleared, the battery must be returned for non-warranty service.

automatically disconnect. The battery will resume normal operation after the short
circuit is removed.
7HPSHUDWXUHSURWHFWLRQȁIf the battery`s temperature exceeds permissible levels the
BMS will disconnect itself automatically. The battery will automatically reconnect once
the temperature has returned to permissible levels.

5.5 Battery Operation
• It is possible to over-discharge the battery if the battery is not used for long time.
In order to prevent over-discharging, the battery shall be charged every 2 months
to maintain a certain voltage range of13.32V~13.6V . For best life, a SOC/ capacity
calibration shall be performed. This calibration method charges the battery fully,
then discharges slightly to prevent an a possible over-discharged state. Letting
a battery sit for months without this procedure can lead to battery problems.
Contact your installer or distributor for more information about this procedure.
• Don’t use organic solvents to clean the battery case.
• A battery is a consumable product with limited cycle life. Please replace it before
the diminished capacity can’t meet the needs of the end user.
• In order to prevent failure of the overcharge protection board, do not charge
for overly long periods of time. After the battery is fully charged, remove it from
the charger. Only use acceptable battery chargers and operate the chargers
according to proper voltages for recommended amounts of time. Failure to do so
can damage the battery and possibly cause a potentially dangerous situation.
• A shallow charge and discharge of the battery ensures that the battery can
be used optimally. Overcharge and over discharge may cause the battery to
